SAFETY-RAZOR.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed March 29. 1907- Serial No. 365.234-

To all whom it may concern:

Be it known that I, JAMES H. BowEN, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Safety-Razor, of which the following is aspecification. I

My invention relates to a razor of the order of a safety, and consistsof a blade which is provided with a longitudinally ex tending groove orchannel, which may be engaged by a member of the head or holder of therazor so as to flex the blade centrally into a groove in the heademployed, while the edge-portions of the same are seated on bearingsurfaces on the head on opposite sides of said groove and which permitssaid blade to be applied in position and removed therefrom by slidablelateral motions, the wall of said groove or channel also serving tostiffen and strengthen the blade, as will be herein described.

Figure 1 represents a perspective view of a razor embodying myinvention. Fig. 2 represents a front elevation thereof, the blade beingremoved. Fig. 3 represents a longitudinal section on line 1ra;, Fig. '1.Fig. 4 represents a face view of the blade of the razor. Fig. 5represents a longitudinal section of a modification. Fig. 6 represents aperspective view of-a modified form of the blade.

Similar lettersof reference indicate corresponding parts in the figures.

Referring to the drawings: A designates a head which is composed of asuitably shaped plate B of metal or other rigid ma-' terial, and rigidarms C, which latter extend from what may be termed the upper end ofsaid plate downwardly in front of the face of said plate'so as tooverhang said front, the lower ends of said arms being inturned, formingthe lips D, with which saidarms are set out from said plate so as toform a space for the reception and location of the blade E, the latterhaving, intermediate of its edges, the longitudinally extending channel,groove or recess F which is adapted to receive said lips D, it beingnoticed that the face of the plate B is cut away sufficiently formingthe recess or groove G, for the occupation-of the back of said channelF, the plate thus having bearing surfaces for both edge-portions ofthe'blade respectively on opposite sides of said groove. Connected withthe plate B,

is the operative handle H, which when the head is formed of cast metalmay be integral with the same.

- On the face of the plate B, adjacent to the bend C, which connects thearm C with said 50 plate, is the projection or hump K on which theadjacent portion of the blade is seated. This removes the inner cuttingedge of the blade from contact with said plate, it being also noticedthat the blade and its channel F 5 In order to apply the blade tothehead, it

is presented to the side of the latter andmoved into the same betweenthe plate B and arms C, with the lips D entering the channel F, thusseating the blade with its opposite edge portions resting on theadjacentbearing surfaces of the plate B, and engaging said lips with the wallsof said groove G, it being noticed that the blade is more or lessflexible so that the lips D, which have their outer terminals out of theplane which connects the opposite bearing surfaces on the plate B of thehead A, press inwardly against the central portion of the blade and soflex the same into said groove G, thus firmly holding the blade at saidcenter while its edge portions are forced against the opposite bearingsurfaces of said plateB, thus doubly insuring the location and seatingof the blade by friction in a firm and comparativelyimmovable manner.The razor is now in condition for use, its shaving edge appearing at theguard J which is provided on the head as usual in razors of the kind.hen the blade is to be removed, it is drawn laterally or in thedirection of the arrow, Fig. 1, it sliding out over the plate B and thewalls of the channel F, and passing the lips D without interference, theblade thus being entirely disconnected, as shown in dotted lines, Fig.l.

Attention is furthermore directed to the groove or channel F, in that itis turned out from the body thereof and its wall forms a bead, or in ameasure a corrugation, which serves to stiffen and strengthen the blade,and thus render the same more durable in its nature.

In Fig. 5, I show the blade reversed, whereby the channel or recess F islocated on the front of the head, and the arms C are grooved, channeledor recessed to receive the wall of said recess and holdingly-engage thesame without producing different results from those in the case.

While I have specified certain means for carrying out my improvements, Ido not wish to be limited exactly to the same, but desire to make suchchanges as may come within the scope of thenovelty involved. As forinstance, the number of beads or corrugations in the blade may beincreased, as shown at F F, Fig. 6, the same belng parallel with thecentral bead or corrugation F, and serving to stiffen the blade to agreat extent intermediate of its cutting edges, so that the blade may bemade light andyet possess strength and durability. If desired, the beadsor corrugations F, F, may be of less depth than the corrugation F. Thecorrugation or corrugations will be found also of importance intempering, sharpening, honing, and stropping the blade, thus preventingwarping of the same, without materially increasing-the cost ofconstruction over a plain blade. Furthermore, the ends of thecorrugation or corrugations present 'broad or blunt surfaces, with whichthe fingers may contact without cutting the latter when'pressing theblade into or out of position.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is zy 1. In a safety razor, incombination, ablade-holding device comprising a rigid head or backing plate having agroove or depressed part providing at each side thereof bearing surfacesconstituting a blade-seat, a flexible blade supported on said blade-seatnear its longitudinal edges, a guard on one side of the backing plateand a rigid extension from its other-side over-hanging the blade.seatand projecting slightly below the plane thereof, whereby the blade isslightly flexed and securely held by friction.

2. A razor of the character stated, composed of a blade having alongitudinal deflection, and a blade-holder comprising a head hollowedout near its center and an arm thereon set out therefrom to slidinglyreceive said blade between them, means on said arm to engage saiddeflection opposite the hollowed out portion and lock the blade on thehead, and a projection on the face of the head between the free end ofsaid arm and the edge of the blade beneath said arm to;

receive said edge of the blade and keep it from contact with the face ofthe head.

3. A razor of the character stated, composed of a blade having aturned-out wall on the face thereon, and a blade-holder composed of ahead and an arm thereon set out therefrom so as to slidingly receivesaid blade between them, means on said arm adapted to engage said walland'lock the blade on the head, and aprojection on the face of said headadjacent to the inner place of connection of said arm with said head, onwhich projection the adjacent portion. of the blade is seated and bywhich the relative cutting edge is removed from said face.

4. In a razor of the character stated, a blade-holder comprising a platehollowed out near its center, an arm extending from an end of said plateand adapted to overhang the face of the same opposite the hollowed outportion, and a projection on said face adjacent to the inner place ofconnection of said arm with said plate at a distance from the free endof said overhangin arm,

said projection being adapted to ho d the relative cutting edge of theblade removed from the face. v

5. A razor of the character stated comprising a head hollowed out nearits center, an arm extending from an end of said head and adapted tooverhang the face thereof, and aiprojection on said face at a distancefrom the free end of said overhanging arm, said projection beingadaptedto have the'adj'acent portion of the blade of the razor seated thereonand hold the relative cutting edge from contact with said face the freeend of said arm being disposed opposite said hollowed out portion.

6. A razor of the character stated comprising a handle, a head hollowedout near its' center, an arm, and a guard, said parts being integral anda projection on the face of said head on which the adjacent portion ofthe'blade is seated and by which the relative cutting edge thereof isremoved from said face, said arm eirtending from'an end of said head andbeing adapted to overhan said face and projection opposite said hol owedout portion and controllingly-engage said blade at a distance from thefreeend of said overhanging arm.
